Old Brass frame Colt
My BIL was just given a Colt cap and ball five shot revolver that appears to be about a .32 caliber. It has the rear sight notch in the front of the hammer and the lever to push the ball in is a small round tube of course connected below the barrell. It has a brass backstrap and trigger guard and I think walnut grips. The address is ____ Colt in Hartford, Ct. and has the serial number of 140,@@@ on three different parts of the pistol. Can anyone tell us what we have? Thanks for all the help.
